Steam is used to heat nutrient medium in a continuous-flow process. Saturated steam at 150°C enters a coil on the outside of the heating vessel and is completely condensed. Medium enters the vessel at 15 °C and leaves at 44 °C Heat losses from the jacket to the surroundings are estimated as 0.22 kW. If the flow rate of medium is 3250 kg h-1 and the heat capacity is Cp=0.9cal g - 1°C - 1, how much steam is required? (Note/hint: hv water at 150 °C = 2113.1kJ kg-1, use unit conversion for kW to kJ s-1 and kcal to k
